BACKGROUND OF THE INVENTION

This invention relates generally to devices having remote controlfunctionality and, more particularly, relates to a system and method forupgrading the remote control functionality of a device.

Devices having functionality for remotely controlling the operation ofmultiple, diverse appliances are well known. To allow such a device tobe used to remotely control appliances that were not considered duringthe time the device was manufactured, it is also known to make thedevice upgradeable. For example, as described in U.S. Pat. No.4,959,810, command codes for use in controlling the operation ofcontrollable appliances can be downloaded into the memory of a devicehaving remote control functionality. As described in U.S. Pat. No.6,104,334 and PCT published application WO 00/17738, the graphicalconsumer interface (“GUI”) of the device can additionally be upgraded toprovided a means by which downloaded command codes can be transmitted tothe remotely controllable appliances.

It is also known to provide customized upgrading of Internet-enableddevices based on a consumer-profile. For example, PCT publishedapplication WO 00/17789 describes a server system that maintains aprofile of a particular end-consumer of network-enabled equipment and adatabase of new technical features for this equipment. In the case wherethere is a match between the consumer-profile and a new technicalfeature, and the consumer indicates a desire to receive notificationregarding updates or sales offers, the consumer is notified via thenetwork of the option to obtain the feature.

SUMMARY OF THE INVENTION

The subject invention is directed to an improved system and method forupgrading the remote control functionality of a device. Generally, amarkup language file is created including a representation ofinformation used to setup the remote control application to communicatewith an appliance. The markup language file may be executed, on thedevice or an intermediate client with which the device is synchronized,to upload the representation of the information to a remote server. Atthe remote server, the uploaded information is used to automaticallydisplay user-selectable, downloadable data files relevant to theidentified appliance. Downloaded data files, which may include commandcodes and/or graphical user interface elements, may be used within thedevice to upgrade the ability of the remote control application tocommunicate with the appliance. The information uploaded to the servermay also be used to generate demographic data regarding consumerpreferences.

DETAILED DESCRIPTION

Referring now to the figures, wherein like reference numerals refer tolike elements, there is illustrated in FIG. 1 a device 10 having remotecontrol functionality. As will be described in greater hereinafter, thedevice 10 is adapted to communicate with a server 11 via a network 13 toreceive upgrade data and/or to exchange information with the server 11.Generally, the server 11 has an associated database 17 in which theinformation and upgrade data (received from the device 10 anddownloadable to the device 10) is maintained. As will be appreciated,the device 10 may exchange communications directly with the server 11 orindirectly by means of an intermediate client 15, such as a personalcomputer. Furthermore, the communication exchanges can be accomplishedusing any suitable wired or wireless protocol.

The underlying platform of the device 10 preferably includes a processor14 coupled to a memory system 16 comprising a combination of ROM memory25, non-volatile read/write memory 24, and RAM memory 26; a key matrix18 in the form of physical buttons; an internal clock and timer 20; atransmission circuit 22; a power supply 28; a touch screen display 30 toprovide visible feedback to and accept input from the user of the device10; and I/O circuitry 32 for allowing the device 10 to exchangecommunications with an external computer such as server 11 and/or client15. Additional input circuitry, such as a barcode reader, may also beutilized. Representative platforms include, but are not limited to,devices such as Web tablets and/or PDAs manufactured by Compaq, HP,Palm, Visor, etc.

As will be appreciated, the memory system 16 includes executableinstructions that are intended to be executed by the processor 14 tocontrol the operation of the device 10. In this manner, the processor 14may be programmed to control the various electronic components withinthe device 10, e.g., to monitor power, to cause the transmission ofsignals, etc. Within the memory system 16, the ROM portion of memory 25is used to store fixed programming and data that remains unchanged forthe life of the product. The non-volatile read/write memory 24, whichmay be FLASH, EEPROM, battery-backed up RAM, “Smart Card,” memory stick,or the like, is provided to store consumer entered setup data andparameters, downloaded data, etc., as necessary. RAM memory is used bythe processor for working storage as well as to hold data items which,by virtue of being backed up or duplicated on an external computer (forexample, the client device 15) are not required to survive loss ofbattery power. While the memory system16 as illustrated comprises allthree classes of memory, it will be appreciated that, in general, such amemory system need not necessarily support all three, and can becomprised of any type of computer-readable media, such as ROM, RAM,SRAM, FLASH, EEPROM, or the like in combination. Preferably, however, atleast part of the memory system 16 should be non-volatile or batterybacked such that basic setup parameters and operating features willsurvive loss of battery power. In addition, such memories may take theform of a chip, a hard disk, a magnetic disk, and/or an optical diskwithout limitation.

For commanding the operation of appliances of different makes, models,and types, the memory system 16 may include a command code library. Thecommand code library is comprised of a plurality of command codes thatmay be transmitted from the device 10 for the purpose of controlling theoperation of an appliance. The memory system 16 may also includesinstructions which the processor 14 uses in connection with thetransmission circuit 22 to cause the command codes to be transmitted ina format recognized by an identified appliance. While the transmissioncircuit 22 preferably utilizes infrared transmissions, it will beappreciated that other forms of wired or wireless transmissions, such asradio frequency, may also be used.

To identify appliances by type and make (and sometimes model) such thatthe device 10 is adapted to transmit recognizable command codes in theformat appropriate for such identified appliances, information may beentered into the device 10. Since methods for setting up a remotecontrol to control the operation of specific appliances are well-known,they will not be described in greater detail herein. Nevertheless, foradditional details pertaining to remote control setup, the reader mayturn to U.S. Pat. Nos. 6,225,938, 4,623,887, 5,872,562, 5,614,906,4,959,810, 4,774,511, and 4,703,359 which are incorporated herein byreference in their entirety.

To cause the device 10 to perform an action, the device 10 is adapted tobe responsive to events, such as a sensed consumer interaction with oneor more keys on the key matrix 18, with the touch screen display 30, ora signal from an external source such as a remote computer. Morespecifically, in response to an event, appropriate instructions withinthe memory system 16 are executed. For example, when a hard or softcommand key is activated on the device 10, the device 10 may read thecommand code corresponding to the activated command key from the memorysystem 16 and transmit the command code to an appliance in a formatrecognizable by the appliance. It will be appreciated that theinstructions within the memory system 16 can be used not only to causethe transmission of command codes to appliances but also to performlocal operations. While not limiting, local operations that may beperformed by the device 10 include favorite channel setup, macro buttonsetup, command function key relocation, etc. Examples of localoperations can be found in U.S. Pat. Nos. 5,481,256, 5,959,751,6,014,092, which are incorporated herein by reference in their entirety.

As discussed, the platform illustrated in the block diagram of FIG. 1comprises a general purpose, processor system which is controllable bysoftware. The software may include routines, programs, objects,components, and/or data structures that perform particular tasks thatcan be viewed as an operating system together with one or moreapplications. The operating system, such as the “Windows CE” brandoperating system or the like, provides an underlying set of managementand control functions which are utilized by applications to offerconsumer functions such as calendar, address book, spreadsheet, notepad,etc., as well as control of appliances. Additional applications can beprovided for use in accessing Internet data, displaying TV guideinformation, and the like. Thus, it should be understood that, in termsof the internal software architecture, the “remote control” applicationmay be but one of several possible applications which may co-existwithin the device 10. It should also be understood that in terms ofproviding operating system functionality, the demarcation betweenportable device and host PC may vary considerably from product toproduct—at one extreme the portable unit may be nothing more than aslave display and input device in wireless communication with a fixedpersonal computer which performs all computational functions, at theother extreme the portable unit may be a fully-functional PC system init's own right complete with local mass storage. It will also beappreciated that in an alternative embodiment, a similar hardwareplatform to that described above may be used in conjunction with ascaled-down operating system to provide remote control functionalityonly, as a standalone application. In all cases, however, the principlesexpressed herein remain the same.

To provide a means by which a consumer can interact with the device 10,the device 10 is provided with software that implements a graphical userinterface. The graphical user interface software may also provide accessto additional software, such as a browser application, that is used todisplay to the consumer items that may be received from an externalcomputer. Such a graphical user interface system is described in pendingU.S. applications Ser. Nos. 60/264,767, 60/334,774, and 60/344,020 allof which are incorporated herein by reference in their entirety.

To support the remote control functionality of the device 10, the server11 includes programming that generally provides an accessible Web sitethrough which the consumer may download upgrade data, exchangeinformation (such as downloading viewer guides, instruction manuals anduploading appliance ownership information), etc. Thus, the Web site mayalso function to capture information regarding the configuration of thedevice 10 as well as information regarding the owner of the device 10.As will become apparent from the description that follows, thisinformation can be aggregated to generate demographic data such as, byway of example, percentage of people owning a particular make and modelof an appliance in a geographic region, percentage of people owning aparticular make and model of an appliance in combination with anappliance of another particular make and model, etc.

To this end, as illustrated in FIG. 2, the application providing theremote control functionality on the device 10 generates and updates amarkup language file in which information utilized by the server 11 iscontained. This markup language file may then be transferred from thedevice 10 to the client 15 as part of a normal synchronization process,such as when a PDA is docked with a PC. The markup language file canthen be executed on the PC to exchange the information with the server11. While the description that follows will assume that thecommunication with the server 11 is being initiated through the client15, it is to be understood that the exchange of information describedhereinafter may also be performed using direct communications betweenthe device 10 and the server 11, such as when the remote controlapplication is hosted on a Web tablet, Internet appliance, or the likehaving integrated Internet and browsing features. In this latter case,it will be appreciated by those of ordinary skill in the art that thefunctions shown in the second and third columns in FIG. 2 (“PDA” and“PC”) will take place within a single device, the distinction betweenthese tasks in this configuration becoming logical rather than physical.

To access downloadable data/information maintained by the server 11, theconsumer accesses a Web site, for example, using a conventional browseron the client 15, whereupon the consumer may be presented with a homepage, an example of which is illustrated in FIG. 3. From this home page,the consumer may navigate to a download access page (e.g., by clickingon the “Personalize My . . . ” link) that provides access to data thatmay be used to upgrade or customize the remote control functionality onthe device 10. If the customer is a first time visitor to the downloadaccess page, the consumer may be requested to register with the Web siteat this time. An exemplary registration page is illustrated in FIG. 4.As can be seen, information captured during the registration process mayinclude information such as consumer name, address, sex, age, maritalstatus, viewing habits, etc. This registration information may bemaintained in the database 17 associated with the server 11. As will beunderstood from the description that follows, the information gatheredduring the Web site registration process may also be used in connectionwith information gathered by the device 10 (and uploaded to the server11) to provide meaningful demographic data.

Once the consumer has successfully registered with the Web site, ifrequired, the consumer can access page(s) that provides access to thedownloadable upgrade and/or customization data. An exemplary downloadpage is illustrated in FIG. 5. Generally, the download page(s) provideaccess to data that can be downloaded to the device 10 to provide, foruse in connection with the remote control application, a collection ofcommand codes for generally controlling a home appliance (e.g., “devicecontrol” downloads), command codes and, possibly GUI elements, forcontrolling a specific operation of a home appliance (e.g., “advancedkey” downloads), and/or GUI elements alone (e.g., “graphics” downloads).By way of further example, activating the link associated with the“advanced key” download results in the display of the advanced keydownload page illustrated in FIG. 6 by which the consumer can accessdownloadable data for specific home appliances owned by the consumer. An“advanced key” in this context means a command which is available on theoriginal device's OEM remote control but which is not included in thestandard set of command functions included in the library that shipswith the universal remote control application. This may occur due todata storage limitations within the universal remote control, newfunctions or features being added by an OEM in the middle of a productlife cycle, presence of little-used features which are important to onlya very small subset of users, etc.

To allow the consumer to configure/update the device 10 using the Website, the consumer may be asked to manually identify the appliance forwhich configure/update data is to be downloaded. For example, asillustrated in FIG. 6, the consumer can manually identify the homeappliance to the Web site by supplying to the Web site (via a text entrybox, pull down menu, or the like) a known setup code for an appliance,an appliance make and model number, or any other suitable informationthat functions as an appliance identifier. To automatically provide homeappliance identity information to the Web site, as yet another means toaccess downloadable data or information of interest, the applicationthat provides the remote control functionality on the device 10 maystore appliance and other information in the markup language file whichinformation is ultimately uploadable to the Web site server 11. By wayof example, as illustrated by the “easy setup” instructions set forth inthe download access page shown in FIG. 6, the consumer need only executethe markup language file to upload the device 10 gathered information tothe Web site server 11. As noted, but not required, it is assumed in thediscussion that follows that the markup language file is resident on theclient 15 where the file was transferred to the client 15 during aconventional synchronization process performed with the device 10.

Turning to FIG. 7, an exemplary markup language (e.g., HTML) filecontaining the device 10 gathered information is illustrated. The markuplanguage file may be created by the remote control application when theremote control application is first invoked on the device 10. Generally,the markup language file includes instructions that, when the file isexecuted, causes a greetings page to be displayed in a Web browserapplication. By way of example, the greetings page, illustrated in FIG.8, may display to the consumer further directions and/or information foruploading information to the Web site. If the consumer is comfortablewith the upload procedure, clicking on an “OK” button can result in theuploading of the device 10 gathered information to the Web site. In thisregard, the uploading of the information can be accomplished using anHTTP post to a Web address that is specified in the markup languagefile. (see line 8 of FIG. 7).

The information uploaded to the Web site may be maintained in fieldswithin the markup language file that are hidden, i.e., not displayed aspart of the greetings page. (see lines 9–17 of FIG. 7). This informationmay include information regarding the consumer, for example, the firstand last name of the consumer. As will be appreciated by those of skillin the art, the consumer information would typically be provided as partof an initialization or registration process when the device 10 is firstactivated, especially when the device 10 is a PDA or the like hosting aWindows brand operating system. The consumer information entered as partof the operating system initialization process would be stored in a filethat is readable by applications running on the device 10, including theone which provides the remote control functionality. Alternatively, theapplication providing the remote control functionality could itselfrequest that the consumer provide this information. This customerspecific information is particularly useful as a cross-reference toinformation obtained during the Web registration process, as is thedevice serial number as described in more detail later.

Further included in the markup language file is information thatidentifies the remote control application and the hardware platform,including versioning. This information can be used by the Web site toensure that compatible data is supplied back to the device 10. As willbe understood by those of skill in the art, this information can beobtained by reading a registry file, by being set as a default value inthe markup language file template, or the like. In cases where a uniqueserial number is assigned to the device 10 at time of manufacture,stored in a non-alterable fixed form, and made accessible to applicationprograms, this is the most convenient and preferred cross-referencevalue to the information provided by the Web registration process. (seeline 10 of FIG. 7). Where such embedded serial numbers are notavailable, a serial number associated with the remote controlapplication software itself, one assigned to the user at Web siteregistration time, etc., may be used as a substitute.

Still further, the markup language file includes data that functions toidentify the one or more appliances the device 10 has been setup tocontrol. This information is particularly found in line 13 of theexemplary markup language file illustrated in FIG. 7 and is dynamicallymaintained as part of the remote control application setup process(i.e., every time the remote control setup process is used to add ordelete a device this file entry may be updated to reflect the newvalues.) In those devices implemented using a “Windows CE” brandoperating system or the like which support automatic synchronization,simply making a change to the file in this manner is sufficient to causean automatic update or synchronization of the PC-side copy of this filethe next time the device is docked or otherwise communicates with it'shost.

To effectively identify the appliance to the server 11, the applianceinformation preferably includes both a device type and number field(shown as four hexidecimal numbers where the first number is indicativeof the appliance type (e.g., TV, VCR, etc.) and the last three numbersare indicative of the specific library of command codes to which theappliance responds (e.g., corresponding to three-digit setup code usedduring the remote control setup process)). In the case where theparticular brand name of the appliance is specified to the device 10during the remote control setup process (e.g., when a setup by brandmethod is utilized), the brand name is also included in the information.Otherwise, the brand name may be set to a null value (i.e., indicated bythe entry “( )”) when it is not possible to discern the brand name fromother setup information (e.g., the setup code “0033” for a “Panasonic”brand TV may also be the setup code for the same TV that is sold undersecondary brand names such as “Quasar” or “Technics” or private labelssuch as “Sears” or “Radio Shack”).

In the case where the consumer has clicked on the “OK” button in thepage illustrated in FIG. 8, the information in the markup language fileis uploaded to the specified Web site address and the information isused to automatically display to the consumer downloads available forthe appliances setup to be controlled using the remote controlapplication. An example download page is illustrated in FIG. 9 whereinlinks are provided to access downloadable data that is specificallyavailable for the equipment the remote control application was setup tocommand, namely, a “Panasonic” brand TV, a “Hughes” brand satellitereceiver, a “Sony” brand stereo receiver, and an unbranded, but specificVCR-like device that has command codes maintained in a libraryidentified by the setup code “0162” (“0a2” in hexadecimal). The downloadpage may also provide instructions to the consumer to cure anyoversights that resulted in an expected appliance not being listed or anappliance being listed in error.

At this time, the consumer may elect to download configuration/downloaddata for a specific appliance by selecting a link to a further downloadpage specific to that appliance. For example, if the consumer clicked onthe link corresponding to the “Hughes” brand satellite receiver asillustrated in FIG. 9, downloads for the “Hughes” satellite receiver,such as advanced key features available, can be automatically presentedto the consumer as illustrated in FIG. 10. The consumer may then choosethe downloads of interest (e.g., by clicking on a corresponding checkbox) and request the initiation of the download process (e.g., byclicking on the “Submit” button). In response, a data file containingthe selected data (i.e., command code data and/or GUI elements) isautomatically downloaded to the client 15 or device 10, as appropriate.In the case where the data is downloaded to the client 15, thedownloaded data may be transferred to the device 10 the next time thedevice 10 is synchronized with the client 15. The new data would then beavailable to the consumer to setup the remote control application to usethe downloaded command code(s) and/or GUI element(s) when the remotecontrol application is set in a mode to control the appliance for whichthe data was downloaded.

To provide a measure of security, it is contemplated that the downloadeddata can be encrypted. For example, the data file can be encrypted usingthe serial number provided during the Web site registration process. Theremote control application would likewise use the serial number todecrypt the data file. Since in the illustrative embodiment the remotecontrol application reads the serial number from internal memory, whichserial number is unalterable, it may be ensured that the data file isonly useful for the device for which it was intended.

The information uploaded to the server 11 may also be maintained withinthe database 17 for use in providing meaningful demographic data. Insome instances, this uploaded information may be cross-referenced withother information stored on the database 17, such as that gatheredduring the Web site registration process. In this regard, meaningfulinformation is received at three points during the process described.Referring once again to FIG. 2, these occur at the time of initialregistration 50 (see also FIG. 4), when execution of the HTML file (seealso FIGS. 7, 8) transfers the consumer's current equipmentconfiguration to the Web server 51, and when the consumer selects 52 theadditional key functions he wishes to download into his remote controlapplication (see also FIG. 10.) Not illustrated in detail butadditionally available to the consumer in an exemplary embodiment is theability to download an entire standard IR code set for a device (asopposed to simply acquiring additional key functions for a device whichalready exists), for example where a new device is released to themarket after the consumer's acquisition of the remote controlapplication. (This is the first choice listed in the display shown inFIG. 5.)

By way of example, the information collected at step 51, when combinedwith the registration information 50 can be used to generate demographicdata such as appliance ownership by brand, by geographical region, bygender, by age, by marital status, by viewing habits, by remote controldevice brand or model (deduced from version and serial number), etc., orany combination of the above parameters—for example, “What percentage ofupgradeable remote control users living within zip codes 90000 to 99999who own a Sony branded satellite receiver are single males under the ageof 25?” This information can also be used to cross-reference ownershipof different equipment types, since the consumer's entire configurationis captured whenever he logs on. By way of further example, questionssuch as “How many satellite subscribers also own a PVR?” or “Whatpercentage of brand ‘x’ televisions also own brand ‘x’ VCRs?” or “Whatproportion of setup code 0033 televisions are branded ‘Panasonic’ andwhat proportion are branded ‘Quasar’?” may be easily answered, with orwithout further sub-categorization as described above. In this regard,it will be appreciated that since this information is captured “live”and is representative of each consumer's current equipmentconfiguration, such reports will reflect “installed base” on an ongoingbasis over the life of a product and may thus provide greater insightthan simple raw initial sales or shipment figures.

The information on specific key data requested at step 52 can providevaluable insight into which key functions are perceived as important bythe users of specific device types or models. This information can beused by manufacturers of universal remote control products to “finetune” the standard function libraries that are pre-loaded into theirproduct at time of shipment. For example, with reference to FIG. 10, ifit is found that a disproportionately large percentage of Hughes NetworkSystems Satellite Receiver (setup code 1142) owners are requesting thekey function “Instant Replay,” this function may be considered forinclusion in the next release of the standard code library for thatdevice. Similarly, the number of accesses to download a newly-releasedproduct may be monitored in order to determine an appropriate time toadd it to standard pre-loaded library offerings.

While specific embodiments of the invention have been described indetail, it will be appreciated by those skilled in the art that variousmodifications and alternatives to those details could be developed inlight of the overall teachings of the disclosure. Accordingly, theparticular arrangement disclosed is meant to be illustrative only andnot limiting as to the scope of the invention which is to be given thefull breadth of the appended claims and any equivalents thereof.
